I n the year 1802 we received specimens of this Achillea, gathered
wild not far from Matlock, Derbyshire, by Mr. Rupp o f
Manchester and Mr. Williams of Norton, near Sheffield. Being
no Linnsean species, nor in any way known to us, we have kept
it long unpublished; but a further search has helped us to the
above synonyms. This has possibly been overlooked in England,
as well as in Switzerland, for a variety of A. Ptarmica, t. 757.
There is no probability of its having escaped from gardens, being
scarcely known, except in a few of the most curious. The
flowers expand about August, and the root is perennial. The
whole herb has the habit and strong scent of the garden A. A^e-
ratum, but the deeply-cut radiating base of the leaves is considerably
different, and the flowers are totally unlike, those of Age-
ralum being not one fifth so large, and extremely numerous, in
repeatedly compound corymbs, of a more yellow colour. The
flowers of our present plant are more like Ptarmica, but smaller
and of a yellowish hue. Willdenow reports it a native of Switzerland.
Can Haller have confounded it under his n. 117 y ? We
have never met with a Swiss specimen. Ray says he cultivated
this species at Cambridge, having received it from London. His
description cannot be mistaken.
